This breaks "git reset --keep" in a subdirectory for me.
I ran "git reset --keep <branch>" in a subdirectory and got:
fatal: BUG: parse_pathspec cannot take no argument in this case
Bisecting points to this commit.
The simplest test case is:
( cd t && ../bin-wrappers/git reset --keep HEAD )
which works on master but not pu.
